Ah, Nautilus, GNOME's default file manager. It's been with us for a long time now, and it has certainly been at the centre of a number of controversies. Do we go with a spatial or a navigational Nautilus? Should we replace the location bar with a breadcrumb bar? And now, it's time to move on. Recently, it has become apparent to many that Nautilus could use a make-over.

Dolphin doesn't really fit KDE either. Dolphin took a lot of hints from GNOME, particularly the philosophy of "remove all functionality that enables to user to operate in a way the developer finds unaesthetic". Fortunately there's still enough classic KDE customizabilty left that it remains usable.
